FEATURES AND SPECIFICATIONS Customized and Standard Small Form-factor Pluggable (SFP) Multi-Port Stacked Cage Assemblies with SlimStack Connectors Provide One-Piece Convenience and Superior Electrical Performance These SFP Multi-Port Stacked Cage Assemblies from Molex provide a simplified one-piece solution to meet customer requirements for high-density SFP module spacing. Available products support up to 4.25Gbps data rates with power-filtering circuitry. Standard versions feature an elastomeric gasket that reduces insertion force into the I/O panel while ensuring a reliable EMI seal. These assemblies feature the Molex Board-to-Board SlimStack connector to maintain signal transmission speeds and minimize costs. Circuit components have been designed into the assemblies to optimize electrical performance. The product offering consists of standard and customized assemblies, tailored to suit customers' applications: belly-to-belly using one spacer board. The interface to the host board is achieved with a 0.635mm (.025”) SlimStack connector. SFP Cage Assemblies Multi-Port Stacked with SlimStack™ Connectors 79527 Styles include an original SFP-chassis style or a version compliant with the ATCA* (Advanced Telecom Computing Architecture) standard, the difference specified by the height of the interface connector. The ATCA version uses a 7.00mm (.276”) height while the standard version uses a 10.00mm (.394”) height connector. Customized Products - include different configurations of SFP cages, along with the addition of power filtering components on the spacer board, customized mechanical outlines or the options of pre-installed LEDs and light pipes. Custom SFP Multi-Port Stacked Assembly Host PCB Side Up with SlimStack Connector Standard Products - begin with two versions which utilize two 1-by-4 SFP cages (series 73927) installed Features and Benefits ■ Single-piece board-to-board assembly provides easy installation and facilitates ordering and inventorying of components ■ High-speed electrical performance tested to 2.5Gbps and 4.25Gbps supports high-speed networking and data exchange equipment ■ Individual electrical customization provides added board components for power filtering, enhanced electrical performance and added LEDs and lightpipes ■ Mechanical customization allows board size to fit customer dimensions and shape and reduces lead time for modification and design changes SFP Multi-Port Stacked Assembly Standard Form Factor Chassis SPECIFICATIONS Reference Information Packaging: Box Mates With: 73929 Copper Patch Cable, 74720 HSSDC2 Copper Pluggable Module and industry-standard optical SFP modules Used With: 0.635mm (.025”) SlimStack Connector Plug on host PCB Designed In: Millimeters Electrical - SFP Connector (74441) Voltage: 30V Current: 0.5A Contact Resistance: 10mΩ max.
